　　Ⅱ.閱讀理解

　　A

　　Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings.

　　The noise that affects sea creatures comes from a number of human activities.It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines.Such noises are added to natural sounds.These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.

　　Decibels (分貝) measured in water are different from those measured on land.A noise of one hundred and twenty decibels on land causes pain to human ears.In water, a decibel level of one hundred and ninety-five would have the same effect.

　　Some scientists have proposed setting a noise limit of one hundred and twenty decibels in oceans.They have observed that noises at that level can frighten and confuse whales.

　　A team of American and Canadian scientists discovered that louder noises can seriously injure some animals.

　　The research team found that powerful underwater explosions were causing whales in the area to lose their hearing.This seriously affected the whales' ability to exchange information and find their way.Some of the whales even died.The explosions had caused their ears to bleed and become infected.

　　Many researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels.They say such a limit would mean an end to important industrial and scientific research.

　　Scientists do not know how much and what kinds of noises are harmful to ocean animals.However, many scientists suspect that noise is a greater danger than they believed.They want to prevent noises from harming creatures in the ocean.

　　16．According to the passage, which of the following is increasingly dangerous to sea creatures?

　　A．The sound of a car.

　　B．The sound of voices.

　　C．Man-made noise pollution.

　　D．The sound of steps.

　　17．According to the passage, natural sounds include all of the following EXCEPT________.

　　A．sounds made by animals themselves

　　B．ocean drilling

　　C．underwater earthquakes

　　C．the breaking of ice fields

　　18．Which of the following is discussed in the third paragraph?

　　A．The same noise level produces a different effect on land and in the ocean.

　　B．Different places may have different types of noises.

　　C．The decibel is not a suitable unit for measuring underwater noise.

　　D．Different ocean animals may have different reactions to noises.

　　19．Which of the following is TRUE of whales?

　　A．They won't be confused by noises.

　　B．They are deaf to noises.

　　C．Their ability to reproduce will be lowered by high-level noises.

　　D．Their hearing will be damaged by high-level noises.

　　20．According to the passage, what will scientists most probably do in the future?

　　A. They will work hard to reduce ocean noise pollution.

　　B．They will protect animals from harmful noises.

　　C．They will try to set a limit of 120 decibels.

　　D．They will study the effect of ocean noise pollution.

　　B

　　The sea has always interested man.From it he can get food, minerals, and treasure.For thousands of years, he could sail on it.But he could not go far beneath its surface.

　　Man wants to explore deep into the sea.However, he is not a fish.He must breathe air, so he can't stay under the water's surface for any length of time.To explore deep water, man faces even more dangers and problems.

　　A diver who wants to stay under water for more than a few minutes must breathe air or a special mixture of gases.He can wear a diving suit and have air pumped to him from above.He can carry a tank of air on his back and breathe through a nose and a mouthpiece.Water weighs 800 times as much as air.Tons of water pushes against a diver deep in the sea.His body is under great pressure.

　　When a diver is under great pressure, his blood takes in some of the gases he breathes.As he rises to surface, the water pressure becomes less.If the diver rises too quickly, the gases in his blood form bubbles.The diver is then suffering from the bends.The bends can cause a diver to double up in pain.They can even kill him.

　　21．On the whole, this passage is about ________.

　　A．special mixtures of gases in deep sea

　　B．the problems man faces in deep-sea diving

　　C．air pressure under the surface of sea water

　　D．a kind of illness that man suffers in the sea

　　22．A diver's body in deep water ________.

　　A．is under great pressure

　　B．is just like that of a fish

　　C．suffers from the bends

　　D．weighs very little

　　23．The passage does not say so, but it makes you think that ________.

　　A．deep-divers should be in good health

　　B．divers explore the deep sea only for treasure

　　C．diving under the water too quickly causes a kind of illness

　　D．there is a special mixture of gases under the sea

　　24．Why does a diver get the bends?

　　A．He tries to do exercises under the water.

　　B．His diving suit weighs too much.

　　C．He comes to the surface too quickly.

　　D．The air in his blood is used up.

　　25．From the passage we can see that ________.

　　A．the sea began to interest man a few years ago

　　B．man is not at home deep in the sea

　　C．all divers will get the bends sooner or later

　　D．the air in the sea water will kill a diver if he is not careful

　　答案

　　課時作業(三十三)

　　Ⅰ.1.A　考查現在分詞作定語。being decorated意為“正在裝修的”，修飾meeting-room。

　　2．A　考查動名詞作主語。此處injure與leg之間是被動關系，故用動名詞的被動形式。

　　3．C　考查現在分詞作定語。turn與page之間是被動關系，being turned意為“正被翻動的”。

　　4．C　考查urge的用法。urge后跟從句時謂語用“(should)＋動詞原形”，should可省略；也可用urge sb. to do sth.。由于urge后跟賓格her，故排除A、D。答案為C。

　　5．A　考查固定短語。be well aware of “對……非常清楚”；be well worth “非常值得”；be content with “對……滿意”；be satisfied with “對……滿意”。句意為：當尤塞恩·博爾特準備在倫敦奧運會衛冕的時候，他很清楚他將為觀眾帶來什么。因此答案為A。

　　6．A　考查副詞辨析。narrowly “勉強地，以毫厘之差”； slightly “稍微地”，強調程度；nearly “接近，幾乎”； lightly “輕輕地；輕松地；容易地；不費力地”。本句意為：令他們欣慰的是，他們的學生剛好勉強從搖晃的大樓中逃脫。

　　7．B　考查形容詞詞義辨析。句意：任何和小孩待過的人都知道男孩和女孩應對相似情況的方式是不同的。be aware of 意識到。

　　8．A　考查副詞辨析。句意為：喜歡聽好音樂是一回事，自己能演奏好又完全是另外一回事。A項表示“完全”；B項very一般用在形容詞、副詞、限定詞前面，也可表示“正是”；C項rather表示“相當，很”，可用于形容詞、副詞、比較級、限定詞以及too等的前面；D項much表示“很多”，可修飾比較級。根據句意及用法選擇A項。

　　9．C　考查短語辨析。in the meantime “同時，在……期間”。句意：你去買水果，同時我來做早餐。at all time “無論何時”，on other hand “另一方面”，均不符合題意。

　　10．C　考查非謂語動詞。can't help doing sth.禁不住/情不自禁做某事，不符合題意；can't help do/to do sth.不能幫助做某事。

　　11．B　考查賓語從句。句意：確保門關上了，且所有的燈都關上了之后，那個男孩打開門進了他的臥室。checked后跟了兩個賓語從句，第一個從句的引導詞that省略了。

　　12．D　考查交際用語。當別人贊賞你的時候，應該從禮貌的角度表示感謝。

　　13．A　考查句子結構及look forward to 的基本用法。本句主語是the foreign friends，you referred to是定語從句，所以謂語動詞使用are，構成現在進行時；短語look forward to中的to是介詞，用動名詞形式作其賓語。

　　14．B　考查scare的用法。句意：在街道的拐角處，一些青年人威脅小學生交出錢來。scare sb.into doing sth.“威脅某人做某事”。

　　15．C　考查副詞用法。句意：當媽媽回顧他們婚姻初期時，她不知道他們是如何在如此少的金錢的情況下順利度過那些日子的。當名詞前有few，little(少), many 或much修飾時用副詞so，而不用such，又因為money為不可數名詞，故選C。

　　Ⅱ.A

　　研究表明，噪聲污染對海洋生物帶來了危險，科學家將來要采取措施拯救海洋生物，阻止噪音對海洋生物的傷害。

　　16．C　細節理解題。由第一段Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings.可知，來自人類的噪聲污染對海洋生物帶來了危險。

　　17．B　細節理解題。由第二段These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.可知，ocean drilling不是自然界的聲音。

　　18．A　細節理解題。由第三段可知，同樣分貝的噪音對海洋和陸地產生的影響不同。

　　19．D　細節理解題。由第六段The research team found that powerful underwater explosions were causing whales in the area to lose their hearing.This seriously affected the whales' ability to exchange information and find their way.Some of the whales even died.可知，水下巨大的爆炸聲會使鯨魚失去聽力，甚至喪生。

　　20．B　判斷推理題。由文章的最后一句話They want to prevent noises from harming creatures in the ocean.可知，科學家將來要采取措施阻止噪音對海洋生物的傷害。

　　B

　　自古以來，海底豐富的資源一直吸引著人類。然而，從事深水潛水探索，卻不是一件輕松的工作。本文向我們介紹的就是深水潛水員所面臨的困難和挑戰。

　　21．B　主旨大意題。由文章結構可以看出，文章首先點明了海洋對人類的重大意義，然后提出了文章要說明的主題：To explore deep water, man faces even more dangers and problems.下文圍繞這一主題作了詳細的說明。

　　22．A　細節理解題。由第三段的最后一句(under great pressure)以及前文的敘述可知。

　　23．A　推理判斷題。最后一段告訴我們：潛水員在深水里要承受巨大的壓力，浮到水面時，水壓驟減，這對人體提出很大的挑戰。由此可以推斷從事深海潛水工作的人，身體應該健康(in good health)。

　　24．C　細節理解題。由最后一段的If the diver rises too quickly…The diver is then suffering from the bends.可知，潛水員得減壓病(the bends)的原因是在海水中上升得太快。

　　25．B　推理判斷題。從文章內容可以知道，在深海潛水時，人會面臨更大的危險和更多的麻煩(more dangers and problems)，包括呼吸、高壓造成的不適，甚至會得減壓病。由此可以判斷：人在深海是很不舒適的。解答此題的關鍵是準確理解選項中at home的意思， 在句中相當于 comfortable and relaxed, at ease。
